External Task not executing when called from Workflow.

hello, i have a submit workflow with an external task that is giving me hard time... it doesnt execute the command at all.

this is my wf: (submit changes which works fine) -> then (external task calls java app which works fine and the java app does what it suppose to do) ->then (external task calls perl script, here the script never gets invoked) and that s the problem...

i think what it is happenning is that once the java app gets invoked, it nevers calls back the workflow to move on to the next task? so it never invokes the perl script?

when i login to TS as master i see all the submit workflows with the status at "javatask" which means that the workflows never finished?
i never cared about it and i just ended them manually because the submit and the java app always worked so i never checked on the perl script...

now if you agree that s the problem, how can i fix it?
i dont have any control over the java app, and i dont think they want to change anything in it, so is there time out that i can set for the java task to move on to the next external task? something like this:

i dont need to wait on the javatask to be done... because it does take time for it, so i just wantd to move to the next task as soon as i invoke the javatask... any ideas or input?

this is where i think the problem is:

I definitely agree - the java app isn't transitioning the workflow so your next task is never getting executed.

There are at least two ways you could approach this:

If you had control over the java app - then modifying it to interact correctly with the workflow would probably be the best solution - but as you don't, I believe either of the above should suffice.

If you don't care, then all you need to do is wrap the JS in Perl, make the first command of the Perl a callback to the success state and run the JS. Should be very easy. You can put a timeout and proceed as well, but this IMHO is cleaner.

yep the "timeout" took care of it Smiley Happy

... but the timeout> has to come after the command> otherwise it throws an error.

and yes have to document this, since i am spending more time figuring out how things are than getting things to work, since the person who work here left the company and there was no knowledge transfer nor documentation Smiley Happy

That is why I prefer a Perl wrapper. You can comment in exactly why you are doing that. The timeout is often used for errors, rather than successful completion of a task.

i am trying to do the wrapper thing too... am i doing the call back correctly?

this is the part that concerns the callback.

use TeamSite::WFworkflow;
use TeamSite::WFtask();

my($jobID) = @ARGV[0];
my($taskID) = @ARGV[1];

my $Task = new TeamSite::WFtask($taskID);

$Task->callBack(0, 'log complete');

i am sure something would say here "read the docs" Smiley Happy

i will if can find them...
i tried perldocs -q WFTask and other things but it keeps saying "no documentation for that or this and that..."

nipper

perldoc TeamSite::WFtask

$Task->CallBack(0,"Chris needs to learn Perl");

Perl is case sensitive

lol very funny Smiley Happy

you still found a way to SAY IT Smiley Very Happy

i think iknow enough perl to do alot but for the case sensative thing sometimes tricks me Smiley Very Happy

thanks NIPPER!
